Core Network Message Prioritization via Interface and Type Markings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 5G core networks prioritize messages based on their source network component, leading to bottlenecks during network failures or reduced performance, as all messages from a single source are assigned the same priority, regardless of type or interface.
Innovation Solution
Customized priority markings are assigned to messages based on their type and interface, allowing for differentiated prioritization to avoid bottlenecks during network outages or reduced performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If priority markings are assigned based on source network component, then message prioritization is simplified, but message processing efficiency deteriorates due to bottlenecks
Solution Approach 1:
The patent applies local quality by assigning different priority markings to different types of messages from the same source network component. Instead of treating all messages from a source equally, the system differentiates priority based on message type (e.g., N1, N2, N3 interfaces) and specific message characteristics, allowing critical messages to be processed ahead of less critical ones from the same source, thereby resolving the bottleneck while maintaining manageable complexity
Solution Approach 2:
The patent implements dynamic priority assignment where priority markings are not static but adapt based on network conditions, message type, and interface requirements. The system dynamically adjusts priority levels to reflect current network performance and message urgency, enabling flexible optimization of message processing efficiency without requiring complex manual configuration
2Ease of operation
If all messages from a single source are assigned the same priority, then priority assignment is simplified, but network performance during failures deteriorates
Solution Approach 1:
The patent differentiates priority markings based on local message characteristics such as message type, interface (N1, N2, N3), and content urgency while messages are in transit through the network. This allows the system to maintain ease of operation at the source (automatic assignment) while achieving differentiated treatment of messages based on their specific properties, thereby improving reliability during network failures without complicating the assignment process
Solution Approach 2:
The system performs preliminary action by pre-defining priority marking rules and classifications for different message types and interfaces before network failures occur. These predefined priority schemes are automatically applied when messages are generated, ensuring that critical messages are already marked with appropriate priority levels before network conditions deteriorate, thus improving failure response without requiring complex real-time decision-making

AI summary
Embodiments of the present disclosure are directed to systems and methods for improved prioritization of messages exchanged within the core network. By providing priority markings customized based on the type of message being sent and/or the interface the message is sent on, a network may work more optimally in the event of network failure or reduced performance of the network.
